This invention relates to oil burners..

An object of thel invention is to provide an Oil burner comprising abase frame of strongand preferably integral construction permitting thepassage of air to the burner :head supported below a combined vapor tubeand baffle plate designed and arranged to control the quantity,direction. and ve'- locity of the air drawn by the suction created.-

v by the combustion at the combined generator and flame spreader. l f fvAnotherobjectof the invention is to prof vide an oil lburnerincludingan integrally .cast generator and flame spreader having a burner head ofnovel and improved construction that will prevent Ithe formation ofcarbon, in combination with a combined vapor tubeand baflleplatesupported abovev the burner lhead and below the generator and flamespreader to control the air ,and to per-y v1 mit vthe flame tocontactwith the generator and flame spreader andwith the inletY andoutlet passages thereof, thus applying heat at three' points andincreasing the operating efficiency with therresult that cleaner andbetter combustion is obtained.

Another object of the invention is to provide an improved oil burner;possessing all Y of the advantages and novel features of con' structionherein mentioned or apparent from the following description, referencelbeing made. to the drawing showing Aa preferred embodiment of theinvention and in which- Fig. 1 is a plan view showing two burners upon asingle base. y Fig. 2 is a side elevation thereof.v

While I have shown two burners mounte upon'a single base it will beunderstood that the number of burners mounted upon a base:

or in adjacentrelationship may be varied as desired. As shown the basecasting is in theform of: an integral frame comprising side members 1Lconnected by endmembers 2, and in case more than one burner is of theendsby crossconnections 3. If -desired, ythe sides, ends and crossconnections of the frame, or anyof them, may be provided with insideflanges .4, ,and the cross wide horizontal connection 5. Notches" 6mounted upon a base connected'intermediatel connections 3 may beunitedby a relativelyv 3 in a vstructure in lwhich more than one burnerlis mounted upon a single base.l The l part of the base casting directlyundereach burner is formed with a generating cup or tray 7 designed andadapted tocontain a quantity of oil for initial combustion-to vaporivethe'oil at'the burner head. The oil passing from the burner head thenbecomes ignited and heatsi the combined generator and llame spreader andcontinues to generate gas until the supply of oil passingthereto isdiscontinued. Y y

A supply vpipe 8 for each .burner is connected with the lowerend of. apassagek 9 forming an integral part lof the base frame. A pipe section10 leads fromvthe' upper end of each passage 9 and supports a combinedgenerator and flame spreader and cooperatp ing parts.V t Y The combinedgenerator and flaine spreader comprises 4an integral casting including awell 11, an inlet 12 connected with the pipe 10, vanda downwardlyextending outlet beforined in the l-owerpedges of the" 13 having avlaterally extended extremityvl'4.;V

l The burner head comprises a number of parts assembled as a untand isremovably connected to the outlet passage 13 to facilivtate replacement.without involving the eX- penseof `a new generator. The designof theburner head is such as to facilitate removalV of any foreignmatterintroduced with the fuel and can be veasily taken apartfor inspectionand cleaning. As shown the assemblyY comprises'tlie tubular partlscrewedl into the lateral extension 14 of the outlet. from thegenerator. The passage 16 in the partV 15 is much smaller ythan theopening throughthe outlet passage 13 and has one or more lateralopenings 17.. The restricted area of the passages 16 and 17 Vas comparedwith the openings through the outlet 13 inf creases the speed ofthe gas.vapoi1 passing. to the vapor tube, withy the result that Ithe deposit ofa carbon formation is reduced to a minimum. The portion. of the tubularpart 15 in which the openings 17 are formed is enclosed in anon-metallic-jacket 18 preferably composedfof mineral steatite, heateduntil' it becomes characterized by a degree.-

having lateral air inlet openings in its sides and having its sidesspaced from the sides of said tray and having a passage upwardly through`one side, a pipe sectionfextending from the upper end of said passage,a combined generator and flame spreader supported by the upper end ofsaid pipe section above said tray,' a burner head supported by and incommunication with said generator and flame spreader between said trayand said generator and spreader, a pair ofde-v tachable baffle plates,and means for sup porting said baifie. plates in connected relationshipbetween said burner head and said generator and spreader.

v7. An oil burner comprising a tray arranged Vto contain a quantity ofcombustible liquid, a frame supporting said tray and through one side, apipe section` extending from the upper end of said passage, a combinedgenerator and flame spreader supportv ed by the upper end 'of said pipesection above said tray, a burner head supported by and `inVcommunication with .saidl generator and flame spreader between saidtray and said generator and spreader, a pair-0f vsemi-tubular elements,and means supporting said semi-tubular elementsrin position to form atube between said burner head and said generator and spreader andpermitting removal of .said elements while the remainder of the oilburner remains assembled.
